There are three steps:<span>Rearrange the equation so "y" is on the left and everything else on the right.Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)<span>Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).</span></span>

Answer:

The value of x = -13

Step-by-step explanation:

Given the expression

\frac{0.2x+1}{2}=-0.8

Multiply both sides by 2

\frac{2\left(0.2x+1\right)}{2}=2\left(-0.8\right)

simplify

0.2x+1=-1.6

Subtract 1 from both sides

0.2x+1-1=-1.6-1

Simplify

0.2x=-2.6

Divide both sides by 0.2

\frac{0.2x}{0.2}=\frac{-2.6}{0.2}

Simplify

x=-13

Therefore, the value of x = -13

Which pair of polygons is similar
DedPeter [7]
I didn’t see an image or anything but I looked it up and it said regular polygons, since they have the sides all the same length they must always be in the same proportions, and their interior angles are always the same.

Analyze the diagram below and complete the instructions that follow. Find a, b, and c.
ahrayia [7]

Answer:

<u>The correct answer is the letter C. </u>

Step-by-step explanation:

We can use the following trigonometric identity:

cos(60)=\frac{6}{b} (1)

cos(45)=\frac{c}{b} (2)

Solving each equation by b and equaling we have:

\frac{6}{cos(60)}=\frac{c}{cos(45)}

\frac{6}{cos(60)}=\frac{c}{cos(45)}

Let's recall that:

cos(45)=\frac{1}{\sqrt{2}}

cos(60)=\frac{1}{2}

Then we have:

c=\frac{cos(45)*6}{cos(60)}

c=\frac{2*6}{\sqrt{2}}

c=\frac{12}{\sqrt{2}}

c=6\sqrt{2}

Using equation (1) we can find b.

cos(60)=\frac{6}{b}  

b=12      

Finally, we can find a using the next equation:

tan(60)=\frac{a}{6}

a=6*tan(60)

a=6\sqrt{3}

<u>Therefore, the correct answer is the letter C. </u>

I hope it helps you!
